Grasshoppper Loading Error

This error is thrown every time I open Grasshopper. It showed up maybe 6 months ago, it doesn’t seem to be affecting any performance or functionality. I’m curious if others are getting this error or how I might solve it.

This is the error message text:

Priority: ModelContentEnablerLoader
{
  The type initializer for 'Grasshopper.Rhinoceros.Model.ModelInstanceDefinition' threw an exception.
  TypeInitializationException
}
